General lighting:
This refers to the light fitting chosen to light up the space, most commonly this would be overhead or ceiling lighting. This form of lighting is most necessary for an interior space so that you can physically see. Overhead light fittings may include spotlights, ceiling-mounted lights, and track lights, all seen as standard general light fittings.
Designers can use these fittings in a reflective lighting plan, and strategically position them most effectively, both to flood light within the space and allocate their locations in the most attractive format possible.
Task Lighting:
As the name suggests this form of lighting is specific to the task at hand. Focusing on the task and design aesthetic, the designer will choose and position light fittings to put a spotlight on the task at hand. This could be kitchens, reception desks, restaurant bars, office desks or bedside tables.
Each area mentioned carries out many tasks, let's take the example of a bedside table in a hotel bedroom, one would need a reading light and/or a lamp so that the guest can wind down, turn off the general overhead lighting and possibly read a book before sleeping. The fitting chosen here would need to be somewhat adjustable on a bracket, arm or fixed–possibly adjustable by dimming to set a calmer ambience. Easy accessibility should also be a priority, one needs to be able to find the switch of this light easily in case it is needed during the night.
Task lights can take many shapes and styles of fittings including pendants, wall lights, reading lights, under-counter lights for receptions and bars. These fittings also can be a feature within the interior design, as these fittings can be fun, utilising an interesting design fitting to create something structural and quirky.
Feature Lighting:
This section of lighting is more architectural, it enhances the user experience.
Here, we are highlighting features that the interior space provides or details that have been designed that need to be lit up. Some examples are built-in shelving, which could be a feature in a restaurant to display sculptures and decorative pieces, designers can use hidden LED strips to backlight these pigeon-holes resulting in a visual impact.
Another example is path lights for stairs or to direct clients to different areas. This helps the client direct themselves through a more in-depth experience.
